You may find the following vim settings useful when using the Powerline
statusline:

setlaststatus=2" Always display the statusline in all windowssetshowtabline=2" Always display the tabline, even if there is only one tabsetnoshowmode" Hide the default mode text (e.g. -- INSERT -- below the statusline)

The Terminus fonts does not have the powerline glyphs and unless someone submits
a patch to the font author, it is unlikely to happen. However, Andre Klärner
came up with this work around: In your ~/.Xdefault file add the following:

I noticed that Source Code Pro has the glyphs there already, but the pixel size
of the fonts play a role in whether or not the > or the < separators showing up
or not. Using font size 12, glyphs on the right hand side of the powerline are
present, but the ones on the left don’t. Pixel size 14, brings the reverse
problem. Font size 13 seems to work just fine.

Once you have updated powerline you generally have the following options:

Restart the application you are using it in. This is the safest one. Will not
work if the application uses powerline-daemon.

For shell and tmux bindings (except for zsh with libzpython): do not do
anything if you do not use powerline-daemon, run powerline-daemon--replace if you do.

Use powerline reloading feature.

Warning

This feature is an unsafe one. It is not guaranteed to work always, it may
render your Python constantly error out in place of displaying powerline
and sometimes may render your application useless, forcing you to
restart.

Do not report any bugs occurred when using this feature unless you know
both what caused it and how this can be fixed.

When using zsh with libzpython use

powerline-reload

Note

This shell function is only defined when using libzpython.

When using IPython use

%powerlinereload

When using Vim use

pypowerline.reload()" or (depending on Python version you are using)py3 powerline.reload()
